I’m running the Hella H4’s on my 1960 GMC with the 4 lamp grille. I assume there is clearance in the back of the 2 lamp system, as there was plenty on my truck. The only modification I had to make was cutting the rubber covers in the center as they kept pushing the connectors off the terminals.

The modification can be seen on post 855 (page 35) of my build thread.

The only improvement I ever found with sealed beams was stepping up to Halogen units. The downside is they burn out faster than any other lamp on the market. I still use them on my high beams as they aren't used frequently, but I went back to standard sealed low beams (before switching to H4s) because I got tired of replacing them every few weeks (I drive with my lights on all the time).
